Magnetic connecting member, in particular for pipe flanges

Abstract

Pair of connecting plates contain on the backside pits fitted with magnets, while at the “connected” position the connecting plates are adjacent, they have identical axially oriented polarization. The pits have passage channels and are laid-out on imaginary circles, where the neighboring magnets have alternating polarization and by pairs and/or threes are covered with magnetic hasps fitted with hasp screws. Centering and disconnection are ensured with the help of centering holes, and possibly centering dimples, fitted with connecting/disconnecting devices. Additional passages placed between two circles with magnets can be added. Possible closing device is attached by spacing posts, spacing screws and ring.
